BTW. There are a few things you may change. - The two added lamps on the left wall do emit light but they don't cast shadows. However, I would use a different less industrial model.- The red signal should be smaller, maybe you add an area to it for a possible green sign as well.- In the back of the scene is this tower like thing with this white pane. It doesn't glow. You can see it more detailed in the third scene.- You have lowered the second level a bit. That's not a problem for the first scene but could be one for the second, because it has a walk mesh for both level.- The ground under the train should be darker since the train does cover it from the most of the light.- On the left side the metal fence before the gates needs to be recreated. It currently looks like a plane with a texture on it.

- Ambient occlusion and (optional) a subtle depth of field could give the image a more plastic look.-I also would cover the scene with a very very very subtle volumetric green/cyan fog. Probably nobody will notice it but I have the feeling it will give a nice result

Anyway it's still very impressive to see the first scene in a true HD remake.
